My first peony bloom of the season just opened. It's a lovely little pink Paeonia mascula.

Paeonia mascula

I posted a picture online and I was surprised how much disbelief there was that I could possibly have a peony blooming so soon in Portland, Oregon. The pics in this post are all from this week.

Paeonia mascula is always the first peony to bloom for me - always in March.

The purpose of this post is show how different peonies can be, at least in my garden. There are a lot of factors influencing peony growth and bloom time.

I admit that I have a few more peonies than the usual Portland gardener might have, so there is a lot happening peony-wise in the garden right now.

At The Lents Farmer, the woody tree peonies (Paeonia suffruticosa), begin leafing out in February and generally bloom the end of April/early May.

I often find their desire for early arrival to be frightening, as I worry that cold weather, frost or snow will get them. With their origins in China, cold weather doesn't seem to phase them. It's still a nail biter for me when Portland weather shifts around drastically in spring.

Herbaceous peonies (Paeonia lactiflora), begin emerging in February. Their red shoots start pushing up the mulch and they start popping out of the ground.

There is a huge disparity among their growth rates. I have some varieties that are now 15" tall with buds clearly visible and some that are barely out of the ground. I assume these differences are varietal and also a little bit location.

Some peonies emerge with little buds hidden in the center, and others wait until later when the weather is warmer to produce buds. So, there are early, mid and late blooming herbaceous peonies. I always think of the herbaceous peonies as about a month behind the tree peonies for bloom time.
